Production Lasted For 11 Years
Most movies are completed within 2-3 years. Actors can’t attach themselves to a movie that takes more than a couple years to get ready, as it’s not financially viable for them. However, for this movie, Tippi and Noel were able to find willing actors and crew.
The movie was produced over some time of 11 years. After the crew was set up and the animals were assembled in 1970, the production began, and it didn’t end till 1981 when the movie was released across Europe.
